HV Power Lab

Separate to the development of the 3-phase controller, handling the power requirement was also required.
The intention is to use simple electronics and deal with the issues of high power electrics separately.

To that end a test-bed vehicle was made by converting a Daihatsu HiJet van.
This was selected due to the access under the floor to the power train.

The van floor was completely removed as was the existing piston-engine power train up to the prop shaft.
Then an ex-milk float motor was added and connected directly to the prop shaft.

Also a wooden bench was fitted in the van over the motor for experimentation purposes.

The basics

This circuit is just for reversing the series wound milk-float motor using contactors:
